DETAILED DESCRIPTION

In the following description, for the purposes of explanation, numerousspecific details are set forth in order to provide a thoroughunderstanding of various exemplary embodiments or implementations of theinvention. As used herein “embodiments” and “implementations” areinterchangeable words that are non-limiting examples of devices ormethods employing one or more of the inventive concepts disclosedherein. It is apparent, however, that various exemplary embodiments maybe practiced without these specific details or with one or moreequivalent arrangements. In other instances, well-known structures anddevices are shown in block diagram form in order to avoid unnecessarilyobscuring various exemplary embodiments. Further, various exemplaryembodiments may be different, but do not have to be exclusive. Forexample, specific shapes, configurations, and characteristics of anexemplary embodiment may be used or implemented in another exemplaryembodiment without departing from the inventive concepts.

Unless otherwise specified, the illustrated exemplary embodiments are tobe understood as providing exemplary features of varying detail of someways in which the inventive concepts may be implemented in practice.Therefore, unless otherwise specified, the features, components,modules, layers, films, panels, regions, and/or aspects, etc.(hereinafter individually or collectively referred to as “elements”), ofthe various embodiments may be otherwise combined, separated,interchanged, and/or rearranged without departing from the inventiveconcepts.

The use of cross-hatching and/or shading in the accompanying drawings isgenerally provided to clarify boundaries between adjacent elements. Assuch, neither the presence nor the absence of cross-hatching or shadingconveys or indicates any preference or requirement for particularmaterials, material properties, dimensions, proportions, commonalitiesbetween illustrated elements, and/or any other characteristic,attribute, property, etc., of the elements, unless specified. Further,in the accompanying drawings, the size and relative sizes of elementsmay be exaggerated for clarity and/or descriptive purposes. When anexemplary embodiment may be implemented differently, a specific processorder may be performed differently from the described order. Forexample, two consecutively described processes may be performedsubstantially at the same time or performed in an order opposite to thedescribed order. Also, like reference numerals denote like elements.

When an element, such as a layer, is referred to as being “on,”“connected to,” or “coupled to” another element or layer, it may bedirectly on, connected to, or coupled to the other element or layer orintervening elements or layers may be present. When, however, an elementor layer is referred to as being “directly on,” “directly connected to,”or “directly coupled to” another element or layer, there are nointervening elements or layers present. To this end, the term“connected” may refer to physical, electrical, and/or fluid connection,with or without intervening elements. Further, the DR1-axis, theDR2-axis, and the DR3-axis are not limited to three axes of arectangular coordinate system, such as the x, y, and z-axes, and may beinterpreted in a broader sense. For example, the DR1-axis, the DR2-axis,and the DR3-axis may be perpendicular to one another, or may representdifferent directions that are not perpendicular to one another.Furthermore, the first and second crossing directions CDR1 and CDR2 maybe perpendicular to one another, or may represent different directionsthat are not perpendicular to one another. For the purposes of thisdisclosure, “at least one of X, Y, and Z” and “at least one selectedfrom the group consisting of X, Y, and Z” may be construed as X only, Yonly, Z only, or any combination of two or more of X, Y, and Z, such as,for instance, XYZ, XYY, YZ, and ZZ. As used herein, the term “and/or”includes any and all combinations of one or more of the associatedlisted items.

Although the terms “first,” “second,” etc. may be used herein todescribe various types of elements, these elements should not be limitedby these terms. These terms are used to distinguish one element fromanother element. Thus, a first element discussed below could be termed asecond element without departing from the teachings of the disclosure.

Spatially relative terms, such as “beneath,” “below,” “under,” “lower,”“above,” “upper,” “over,” “higher,” “side” (e.g., as in “sidewall”), andthe like, may be used herein for descriptive purposes, and, thereby, todescribe one elements relationship to another element(s) as illustratedin the drawings. Spatially relative terms are intended to encompassdifferent orientations of an apparatus in use, operation, and/ormanufacture in addition to the orientation depicted in the drawings. Forexample, if the apparatus in the drawings is turned over, elementsdescribed as “below” or “beneath” other elements or features would thenbe oriented “above” the other elements or features. Thus, the exemplaryterm “below” can encompass both an orientation of above and below.Furthermore, the apparatus may be otherwise oriented (e.g., rotated 90degrees or at other orientations), and, as such, the spatially relativedescriptors used herein interpreted accordingly.

The terminology used herein is for the purpose of describing particularembodiments and is not intended to be limiting. As used herein, thesingular forms, “a,” “an,” and “the” are intended to include the pluralforms as well, unless the context clearly indicates otherwise. Moreover,the terms “comprises,” “comprising,” “includes,” and/or “including,”when used in this specification, specify the presence of statedfeatures, integers, steps, operations, elements, components, and/orgroups thereof, but do not preclude the presence or addition of one ormore other features, integers, steps, operations, elements, components,and/or groups thereof. It is also noted that, as used herein, the terms“substantially,” “about,” and other similar terms, are used as terms ofapproximation and not as terms of degree, and, as such, are utilized toaccount for inherent deviations in measured, calculated, and/or providedvalues that would be recognized by one of ordinary skill in the art.

Various exemplary embodiments are described herein with reference tosectional and/or exploded illustrations that are schematic illustrationsof idealized exemplary embodiments and/or intermediate structures. Assuch, variations from the shapes of the illustrations as a result, forexample, of manufacturing techniques and/or tolerances, are to beexpected. Thus, exemplary embodiments disclosed herein should notnecessarily be construed as limited to the particular illustrated shapesof regions, but are to include deviations in shapes that result from,for instance, manufacturing. In this manner, regions illustrated in thedrawings may be schematic in nature and the shapes of these regions maynot reflect actual shapes of regions of a device and, as such, are notnecessarily intended to be limiting.

As customary in the field, some exemplary embodiments are described andillustrated in the accompanying drawings in terms of functional blocks,units, and/or modules. Those skilled in the art will appreciate thatthese blocks, units, and/or modules are physically implemented byelectronic (or optical) circuits, such as logic circuits, discretecomponents, microprocessors, hard-wired circuits, memory elements,wiring connections, and the like, which may be formed usingsemiconductor-based fabrication techniques or other manufacturingtechnologies. In the case of the blocks, units, and/or modules beingimplemented by microprocessors or other similar hardware, they may beprogrammed and controlled using software (e.g., microcode) to performvarious functions discussed herein and may optionally be driven byfirmware and/or software. It is also contemplated that each block, unit,and/or module may be implemented by dedicated hardware, or as acombination of dedicated hardware to perform some functions and aprocessor (e.g., one or more programmed microprocessors and associatedcircuitry) to perform other functions. Also, each block, unit, and/ormodule of some exemplary embodiments may be physically separated intotwo or more interacting and discrete blocks, units, and/or moduleswithout departing from the scope of the inventive concepts. Further, theblocks, units, and/or modules of some exemplary embodiments may bephysically combined into more complex blocks, units, and/or moduleswithout departing from the scope of the inventive concepts.

Unless otherwise defined, all terms (including technical and scientificterms) used herein have the same meaning as commonly understood by oneof ordinary skill in the art to which this disclosure is a part. Terms,such as those defined in commonly used dictionaries, should beinterpreted as having a meaning that is consistent with their meaning inthe context of the relevant art and should not be interpreted in anidealized or overly formal sense, unless expressly so defined herein.

FIG. 1 is a perspective view illustrating a display device DD accordingto an exemplary embodiment. As shown in FIG. 1 , the display device DDmay include a display surface DD-IS, which is used to display an imageIM. The display surface DD-IS may be defined to be parallel to a firstdirection axis DR1 and a second direction axis DR2. A direction normalto the display surface DD-IS (i.e., a thickness direction of the displaydevice DD) will be referred to as a third direction axis DR3.

In the following description, the third direction axis DR3 may be usedto differentiate a front or top surface of each element from a back orbottom surface. However, directions indicated by the first to thirddirection axes DR1, DR2, and DR3 may be just an example. Hereinafter,first to third directions may be directions indicated by the first tothird direction axes DR1, DR2, and DR3, respectively, and will beidentified with the same reference numbers.

In FIG. 1 , the display device DD is illustrated to have a flat displaysurface DD-IS, but the exemplary embodiments are not limited thereto.The display surface DD-IS of the display device DD may have a curved orthree-dimensional shape. In the case where the display device DD has thethree-dimensional display surface DD-IS, the display surface DD-IS mayinclude a plurality of display regions that are oriented in differentdirections. For example, the display device DD may have a displaysurface that is shaped like that of a polygonal pillar.

In the exemplary embodiment, the display device DD may be a rigiddisplay device. However, the exemplary embodiments are not limitedthereto, and in an exemplary embodiment, the display device DD may be aflexible display device. The flexible display device may include afoldable display device or a bendable display device with a bendableportion.

In the exemplary embodiment, the display device DD, which can be usedfor a cellphone terminal, is exemplarily illustrated. Although notshown, the cellphone terminal may further include an electronic module,a camera module, a power module, and so forth, which are mounted on amainboard and are provided in a bracket or case, along with the displaydevice DD. The display device DD may be used for large-sized electronicdevices (e.g., television sets and monitors) or small- or medium-sizedelectronic devices (e.g., tablets, car navigation systems, gamemachines, and smart watches).

As shown in FIG. 1 , the display surface DD-IS may include an imageregion DD-DA, which is used to display the image IM, and a bezel regionDD-NDA, which is adjacent to the image region DD-DA. The bezel regionDD-NDA may not be used to display an image. As an example of the imageIM, icon images are shown in FIG. 1 .

As shown in FIG. 1 , the image region DD-DA may be substantially arectangular or tetragonal shape. The expression “substantiallyrectangular or tetragonal shape” may refer to not only a rectangle shapein the mathematical context but also a rectangular or tetragonal shapewhose vertex or corner has a rounded or curved shape, not a sharp shape.

The bezel region DD-NDA may enclose the image region DD-DA. However, theexemplary embodiments are not limited thereto, and in an exemplaryembodiment, the image region DD-DA and the bezel region DD-NDA may bedesigned to have other shapes. The bezel region DD-NDA may be disposednear only one of sides of the image region DD-DA. The bezel regionDD-NDA may not be exposed to the outside, depending on the connectionstructure between the display device DD and other elements of anelectronic device.

FIGS. 2A, 2B, 2C, and 2D are sectional views each illustrating thedisplay device DD according to an exemplary embodiment. FIGS. 2A, 2B,2C, and 2D illustrate cross sections, which are parallel to a planedefined by the second direction axis DR2 and the third direction axisDR3. To provide better understanding of a stacking structure of thedisplay device DD, the display device DD is illustrated in a simplifiedmanner in FIGS. 2A, 2B, 2C, and 2D.

In an exemplary embodiment, the display device DD may include a displaypanel, an input sensor, an anti-reflector, and a window. At least twoelements of the display panel, the input sensor, the anti-reflector, andthe window may be formed by a successive process or may be combined witheach other by an adhesive member. An adhesive member ADS may be atransparent adhesive member, such as a pressure sensitive adhesive (PSA)film, an optically clear adhesive (OCA) film, or an optically clearresin (OCR) film. In various embodiments to be described below, theadhesive member may be a typical adhesive material or a typical gluingagent. In an exemplary embodiment, the anti-reflector and the window maybe replaced with other elements or may be omitted.

In FIGS. 2A, 2B, 2C, and 2D, if an element (e.g., one of the inputsensor, the anti-reflector, and the window) is formed on another elementthrough a successive process, the element will be referred to as a“layer”. If an element (e.g., one of the input sensor, theanti-reflector, and the window) is combined with another element by anadhesive member, the element will be referred to as a “panel”. Theelement described with the term “panel” may include a base layer (e.g.,a synthetic resin film, a composite film, or a glass substrate)providing a base surface, whereas the element described with the term“layer” may not have the base layer. In other words, the elementdescribed with the term “layer” may be placed on a base surface that isprovided by another element. Hereinafter, the input sensor, theanti-reflector, and the window may be referred to as an input-sensingpanel ISP, an anti-reflection panel RPP, and a window panel WP or aninput sensing layer ISL, an anti-reflection layer RPL, and a windowlayer WL, according to the presence or absence of the base layer.

As shown in FIG. 2A, the display device DD may include a display panelDP, an input sensing layer ISL, an anti-reflection panel RPP, and awindow panel WP. The input sensing layer ISL may be directly disposed onthe display panel DP. In the present specification, the expression “anelement B may be directly disposed on an element A” means that anyadhesive layer/member is not disposed between the elements A and B. Inthis case, the element B may be formed on a base surface, which isprovided by the element A, through a successive process, after theformation of the element A.

The display panel DP and the input sensing layer ISL, which is directlydisposed on the display panel DP, may be defined to as a display moduleDM. The adhesive member ADS may be disposed between the display moduleDM and the anti-reflection panel RPP and between the anti-reflectionpanel RPP and the window panel WP.

The display panel DP may generate an image, and the input sensing layerISL may obtain information on coordinates of an external input (e.g., atouch event). Although not shown, the display module DM may furtherinclude a protection member disposed on a bottom surface of the displaypanel DP. The protection member and the display panel DP may be combinedto each other by an adhesive member. The display devices DD, which willbe described with reference to FIGS. 2B, 2C, and 2D, may also includethe protection member.

According to an exemplary embodiment, the display panel DP may be alight-emitting type display panel, but the exemplary embodiments are notlimited to a specific type of the display panel DP. For example, thedisplay panel DP may be an organic light emitting display panel or aquantum dot light-emitting display panel. An emission layer of theorganic light emitting display panel may be formed of or include anorganic light emitting material. An emission layer of the quantum dotlight-emitting display panel may include quantum dots and/or quantumrods. For the sake of simplicity, the description that follows willrefer to an example in which the display panel DP is the organic lightemitting display panel.

The anti-reflection panel RPP may reduce reflectance of an externallight that is incident from an outer space to the window panel WP. In anexemplary embodiment, the anti-reflection panel RPP may include a phaseretarder and a polarizer. The phase retarder may be of a film type or aliquid crystal coating type and may include a λ/2 phase retarder and/ora λ/4 phase retarder. The polarizer may also be of a film type or aliquid crystal coating type. The polarizer of the film type may includean elongated synthetic resin film, whereas the polarizer of the liquidcrystal coating type may include liquid crystals arranged with aspecific orientation. The phase retarder and the polarizer may furtherinclude a protection film. At least one of the phase retarder, thepolarizer, or the protection film thereof may be defined as a base layerof the anti-reflection panel RPP.

In an exemplary embodiment, the anti-reflection panel RPP may includecolor filters. The color filters may have a specific orientation orarrangement. The arrangement of the color filters may be determined inconsideration of colors of lights to be emitted from pixels in thedisplay panel DP. The anti-reflection panel RPP may further include ablack matrix adjacent to the color filters.

In an exemplary embodiment, the anti-reflection panel RPP may include adestructive interference structure. For example, the destructiveinterference structure may include a first reflection layer and a secondreflection layer, which are provided on different layers.

The emission regions of the n-th emissionrow PXLn may be shifted from the emission regions of the (n+2)-themission row PXLn+2, in the second direction DR2, by a length of asingle emission region.

The third color emission regions PXA-G may be disposed in each of the(n+1)-th emission row PXLn+1 and the (n+3)-th emission row PXLn+3. Theemission regions of the n-th emission row PXLn and the emission regionsof the (n+1)-th emission row PXLn+1 may be disposed in a staggeredmanner with respect to each other. The emission regions of the (n+2)-themission row PXLn+2 and the emission regions of the (n+3)-th emissionrow PXLn+3 may be disposed in a staggered manner with respect to eachother.

The emission regions of the n-th emission row PXLn and the emissionregions of the (n+2)-th emission row PXLn+2 may be disposed tocorrespond to each other. A virtual line VL1 connecting center pointsB-P of the emission regions, which constitute a specific one column inthe n-th emission rows PXLn, e.g. a first emission row and a fourthemission row, may be the same as a virtual line VL1 connecting centerpoints R-P of the emission regions, which constitute the specific columnin the (n+2)-th emission row PXLn+2 e.g. a third emission row and asixth emission row. The emission regions of the (n+1)-th emission rowPXLn+1 and the emission regions of the (n+3)-th emission row PXLn+3 maybe disposed to correspond to each other. A virtual line VL2 connectingcenter points G1-P of the emission regions, which constitute a specificcolumn in the (n+1)-th emission row PXLn+1, may be the same as a virtualline VL2 connecting center points G2-P of the emission regions, whichconstitute the specific column in the (n+3)-th emission row PXLn+3.

As a result, one of the third color emission regions PXA-G, which isincluded in each of the (n+1)-th emission row PXLn+1 and the (n+3)-themission row PXLn+3, may be enclosed by two first color emission regionsPXA-B and two second color emission regions PXA-R. Each of the emissionregions PXA-B and PXA-R, which are included in each of the n-th emissionrow PXLn and the (n+2)-th emission row PXLn+2, may be enclosed by fourthird color emission region PXA-G.

The emission regions of the n-th emission row PXLn and the emissionregions of the (n+2)-th emission row PXLn+2 may be disposed tocorrespond to each other. A virtual line VL1 connecting center pointsB-P of the emission regions, which constitute a specific one column inthe n-th emission rows PXLn, e.g. a first emission row and a fifthemission row, may be the same as a virtual line VL1 connecting centerpoints R-P of the emission regions, which constitute the specific columnin the (n+2)-th emission row PXLn+2 e.g. a third emission row and aseventh emission row. The emission regions of the (n+1)-th emission rowPXLn+1 and the emission regions of the (n+3)-th emission row PXLn+3 maybe disposed to correspond to each other. A virtual line VL2 connectingcenter points G1-P of the emission regions, which constitute a specificcolumn in the (n+1)-th emission row PXLn+1, may be the same as a virtualline VL2 connecting center points G2-P of the emission regions, whichconstitute the specific column in the (n+3)-th emission row PXLn+3.

As described above, the plurality of the emission regions PXA-B, PXA-R,and PXA-G may be classified into a plurality of emission rows PXLn,PXLn+1, PXLn+2, and PXLn+2, based on the first and second directions DR1and DR2. The plurality of the emission regions PXA-B, PXA-R, and PXA-Gmay be classified into a plurality of emission rows PXLo and PXLe, basedon the first crossing direction CDR1 and the second crossing directionCDR2. The emission rows PXLo and PXLe may include odd-numbered emissionrows PXLo and even-numbered emission rows PXLe.

The odd-numbered emission rows PXLo may have the same arrangement of theemission regions, and the even-numbered emission rows PXLe may have thesame arrangement of the emission regions. One group of the odd-numberedemission rows PXLo and the even-numbered emission rows PXLe may includethe first color emission regions PXA-B and the third color emissionregions PXA-G, which are alternately arranged in the first crossingdirection CDR1. Another group of the odd-numbered emission rows PXLo andthe even-numbered emission rows PXLe may include the second coloremission regions PXA-R and the third color emission regions PXA-G, whichare alternately arranged in the first crossing direction CDR1. The thirdcolor emission regions PXA-G of the odd-numbered emission rows PXLo andthe third color emission regions PXA-G of the even-numbered emissionrows PXLe may be disposed in a staggered manner with respect to eachother in the first crossing direction CDR1 or the second crossingdirection CDR2.

The emission rows PXLo and PXLe may includeodd-numbered emission rows PXLo and even-numbered emission rows PXLe.

A border region between the first sensor unit SP1 and the second sensorunit SP2 is illustrated in FIG. 7C. A border line BDL may be animaginary line, which is illustrated to indicate a border between thefirst sensor unit SP1 and the second sensor unit SP2. The mesh linesMSL1 and MSL2 may be formed on a plane provided by the second insulatinglayer IS-IL2, and then, the mesh lines MSL1 and MSL2 may be partiallyremoved to form the first sensor unit SP1, the second sensor unit SP2,and the second connection portion CP2. In an exemplary embodiment,cutting points 10 and 20, along with the three groups of mesh openingsMH-B, MH-R, and MH-G, may be formed through a process of etching aconductive layer, and the mesh pattern may be formed as a result of theprocess.

A virtual line VL10 connecting center points B-P and G2-P (or G1-P) ofthe emission regions of the odd-numbered emission rows PXLo may beparallel to a virtual line VL20 connecting center points R-P and G1-P(or G1-P) of the emission regions of the even-numbered emission rowsPXLe. The virtual line VL10 and the virtual line VL20 may be extended ina direction that is same as an extension direction of the first meshlines MSL1.

The border line BDL may be substantially extended in the first crossingdirection CDR1 or the second crossing direction CDR2. An extensiondirection of the border line BDL may vary depending on where the borderline BDL is formed among the first sensor unit SP1 and the second sensorunit SP2. FIG. 7C illustrates an example, in which the border line BDLis deformed to have a zigzag shape or a serpentine shape. In anexemplary embodiment, the border line BDL may be a line shape extendingin the first crossing direction CDR1 or the second crossing directionCDR2.

FIGS. 8A and 8B are plan views each illustrating disposition of the unitregion UA relative to sensor units SP1 and SP2. FIGS. 8C, 8D, 8E, and 8Fare plan views each illustrating the unit region UA according to anexemplary embodiment.

FIGS. 8A and 8B briefly illustrate two first sensor units SP1 and twosecond sensor units SP2 which are disposed around a single crossingregion. In the following description of FIGS. 8A and 8B, the connectionportions CP1 and CP2 will be neglected. Since the first connectionportion CP1 is disposed on a plane different from the first sensor unitSP1 and the second sensor unit SP2 and the second connection portion CP2has a relatively small area, the connection portions CP1 and CP2 may notaffect the arrangement of the cutting points in the unit region UA.Therefore, the following description will be focused on a single secondsensor unit SP2.

The second sensor unit SP2 may include a plurality of the unit regionsUA. The unit region UA may be a region, in which cutting points to bedescribed below are arranged according to a specific rule. As shown inFIG. 8A, the second sensor unit SP2 may be divided into a plurality ofthe unit regions UA.

As shown in FIG. 8A, a plurality of emission regions PXA may be disposedin the unit region UA. The emission regions PXA may be arranged to forma p-by-p matrix in the second sensor unit SP2. The emission regions PXAmay be arranged to form a q-by-q matrix in the unit region UA. Here, pis a natural number, and q is a natural number less than p. The q may bea divisor of p. The p-by-p matrix and the q-by-q matrix may be definedbased on the first and second crossing directions CDR1 and CDR2.

However, the exemplary embodiments are not limited thereto, and in anexemplary embodiment, the plurality of the unit regions UA may bedisposed in only a center region CAA of the second sensor unit SP2, asshown in FIG. 8B. In this case, the number q may not be a divisor of p.In addition, a border unit region UA-B may be defined in a border regionbetween the first sensor units SP1 and second sensor units SP2. Inaddition, the border unit region UA-B may be defined in a region, whichis positioned between different electrodes (e.g., see FIG. 12B), and inwhich a border line (e.g., the border line BDL of FIG. 7C) can bedefined besides the border region between the first sensor units SP1 andsecond sensor units SP2.

The border unit region UA-B may be a region, in which the cutting pointsare arranged in a manner similar to those in the unit region UA. Theborder unit region UA-B may include the same cutting points as those ofthe unit region UA and may further include the first border points 10and the second border points 20 shown in FIG. 7C. Some of the first andsecond border points 10 and 20 may replace the cutting points of theunit region UA.

An example of the input sensor including the first and second electrodegroups EG1 and EG2 have been described with reference to FIGS. 6A, 6B,6C, 6D, 7A, 7B, 7C, 8A, and 8B, but the exemplary embodiments are notlimited thereto. In an exemplary embodiment, the input sensor mayinclude only one group of electrodes. The input sensor may include atouch sensor sensing an external input in a self-capacitance manner.

The first sensor unit SP1 and the second sensor unit SP2 shown in FIG.8B may be included in one group of electrodes. The first sensor unit SP1and the second sensor unit SP2 may be electrode spaced apart from eachother. A signal line is connected to each of the first sensor unit SP1and the second sensor unit SP2. Here, unlike that shown in FIG. 6A, theinput sensor including only one group of electrodes may include only oneconductive layer.

Referring to FIG. 8C, a plurality of cutting points 1, 2, 3, and 4disposed in the unit region UA are illustrated. In the followingdescription of the sensing electrode with reference to FIGS. 7A, 7B, and7C, the cutting points 1, 2, 3, and 4 are not shown, but a plurality ofthe cutting points 1, 2, 3, and 4 may be defined in the mesh lines MSL1and MSL2 of the sensing electrode according to an exemplary embodiment.In the case where, as shown in FIGS. 7A, 7B, and 7C, the cutting points1, 2, 3, and 4 are not disposed, reflectance of a source light reflectedfrom the mesh lines MSL1 and MSL2 may be substantially the same,regardless of a viewing angle.

The plurality of the cutting points 1, 2, 3, and 4 in the unit region UAmay be disposed such that the mesh lines MSL1 and MSL2 are connected toeach other to form a single electrode. That is, the mesh lines MSL1 andMSL2 may be cut by the cutting points 1, 2, 3, and 4, but the mesh linesMSL1 and MSL2 constituting at least one sensor unit SP1 or SP2 (e.g.,see FIG. 7A) may be connected to each other.

Referring to FIG. 8C, a plurality of cutting points 1, 2, 3, and 4disposed in the unit region UA are illustrated. In the above descriptionof the sensing electrode with reference to FIGS. 7A, 7B, and 7C, thecutting points 1, 2, 3, and 4 are not shown, but a plurality of thecutting points 1, 2, 3, and 4 may be defined in the mesh lines MSL1 andMSL2 of the sensing electrode according to an exemplary embodiment. Inthe case where, as shown in FIGS. 7A, 7B, and 7C, the cutting points 1,2, 3, and 4 are not disposed, reflectance of a source light reflectedfrom the mesh lines MSL1 and MSL2 may be substantially the same,regardless of a viewing angle.

In the unit region UA, the first cutting points 1 and 2 may be definedin the first and second mesh lines MSL1 and MSL2, respectively, and thesecond cutting points 3 and 4 may be defined in the first and secondmesh lines MSL1 and MSL2, respectively. Hereinafter, the first cuttingpoint of the first mesh lines MSL1 may be defined as a first point 1,the first cutting point of the second mesh lines MSL2 may be defined asa second point 2, the second cutting point of the first mesh lines MSL1may be defined as a third point 3, and the second cutting point of thesecond mesh lines MSL2 may be defined as a fourth point 4.

Since the first to fourth points 1 to 4 are disposed in the unit regionUA, a difference in visibility of the mesh lines MSL1 and MSL2 may bereduced, compared with the case that the cutting points are randomlydisposed. The first to fourth points 1 to 4 may have high reflectance toa source light, compared with other regions of the mesh line. Brightnessseen by a user may be high in a direction or viewing angle, in whichrelatively more cutting points are disposed. Since the cutting pointsare not concentrated in a specific direction, it may be possible toreduce a difference in visibility of the mesh lines MSL1 and MSL2according to a viewing angle.

Furthermore, reflectance may be relatively high at the first borderpoint 10 and the second border point 20 described with reference to FIG.7C, but since the first to fourth points 1 to 4 are disposed in thefirst sensor unit SP1 and the second sensor unit SP2, it may be possibleto suppress or prevent the border line BDL (e.g., see FIG. 7C) frombeing recognized by a user. In other words, the first to fourth points 1to 4 may allow an internal reflectance of the first and second sensorunits SP1 and SP2 to be increased to a level that is similar to thereflectance of the border region shown in FIG. 7C.

Referring to FIG. 8C, in the unit region UA, the number of the firstpoint 1 may be equal to the number of the second point 2. FIG. 8Cillustrates an example, in which four first points 1 and four secondpoints 2 are disposed. If, in the unit region UA, a source light isemitted from only the first color emission region PXA-B, reflectance ofthe source light of the first color, which is measured in the firstcrossing direction CDR1, may be substantially equal to reflectance ofthe source light of the first color, which is measured in the secondcrossing direction CDR2.

Furthermore, in the unit region UA, the number of the third point 3 maybe equal to the number of the fourth point 4. As a result, the numbersof the first to fourth points 1 to 4 may be the same. Reflectance valuesof the source lights of the second and third colors may be the same,regardless of crossing direction.

Referring to FIG. 8C, the unit region UA may include a first sub-regionSUA1, a second sub-region SUA2, a third sub-region SUA3, and a fourthsub-region SUA4. Each of the first, second, third, and fourthsub-regions SUA1, SUA2, SUA3, and SUA4 may include emission regions,which are arranged to form a k-by-k matrix. The k-by-k matrix may be setbased on the first crossing direction CDR1 and the second crossingdirection CDR2.

The number k is a natural number that is coprime to h. Here, h may bethe number of repeated emission regions. In the exemplary embodiment,the emission regions may constitute a plurality of repeatedly-arrangedemission groups, in each of which one first color emission region PXA-B,one second color emission region PXA-R, and two third color emissionregions PXA-G are arranged in a specific arrangement. A repletion unitRU is separately illustrated in FIG. 8C. Thus, the number h in theexemplary embodiment is four. As shown in FIG. 8C, the number k in theexemplary embodiment is three. The number k may be a divisor of p,described with reference to FIG. 8A.

In an exemplary embodiment, the emission regions may constitute aplurality of repeatedly-arranged emission groups, in each of which onefirst color emission region PXA-B, one second color emission regionPXA-R, one third color emission region PXA-G, and one fourth coloremission region are arranged in a specific arrangement. One of the twothird color emission regions PXA-G in FIG. 8C may be replaced with thefourth color emission region. The fourth color may be yellow or white.

The third color emission region PXA-G may be disposed at a center ofeach of two sub-regions of the first, second, third, and fourthsub-regions SUA1, SUA2, SUA3, and SUA4, the first color emission regionPXA-B may be disposed at a center of other sub-region of the first,second, third, and fourth sub-regions SUA1, SUA2, SUA3, and SUA4, andthe second color emission region PXA-R may be disposed at a center ofthe remaining sub-region of the first, second, third, and fourthsub-regions SUA1, SUA2, SUA3, and SUA4. Referring to FIG. 8C, the thirdcolor emission region PXA-G may be disposed at centers of the second andfourth sub-regions SUA2 and SUA4. The second and fourth sub-regions SUA2and SUA4 may face each other in the second direction DR2.

The second and third points 2 and 3 may be disposed in the secondsub-region SUA2, which is one sub-region of the two sub-regions. Thefirst and fourth points 1 and 4 may be disposed in the fourth sub-regionSUA4, which is the other sub-region of the two sub-regions. The firstand second points 1 and 2 may be disposed in the first sub-region SUA1,which is the other sub-regions. The third and fourth points 3 and 4 maybe disposed in the third sub-region SUA3, which is the remainingsub-region.

FIG. 8D illustrates the unit region UA (hereinafter, defined as a secondembodiment), which is different from the unit region UA shown in FIG. 8C(hereinafter, defined as a first embodiment) in terms of the arrangementof the cutting points 1, 2, 3, and 4.

FIG. 13B is a plan viewillustrating the input sensing layer ISL according to an exemplaryembodiment. FIG. 14A is a perspective view illustrating the displaymodule DM according to an exemplary embodiment. FIG. 14B is a plan viewillustrating the input sensing layer ISL according to an exemplaryembodiment. Hereinafter, for concise description, an element previouslydescribed with reference to FIGS. 1, 2A, 2B, 2C, 2D, 3A, 3B, 4, 5A, 5B,6A, 6B, 6C, 6D, 7A, 7B, 7C, 8A, 8B, 8C, 8D, 8E, 8F, 9A, 9B, 9C, 9D, 10A,10B, 11A, 11B, 11C, 11D, 12A, 12B, and 12C may be identified by the samereference number without repeating an overlapping description thereof.

As shown in FIG. 13A, when viewed in a plan view, a notch region NTAhaving an inward concave shape may be defined in the display module DM.The notch region NTA may be defined in each of the display panel DP andthe input sensing layer ISL, but it is unnecessary for such notchregions NTA to have the same. The notch region NTA may be defined nearan intermediate region in the second direction DR2. However, it isunnecessary for the notch region NTA to be disposed at the middle point.

As shown in FIG. 13B, the presence of the notch region NTA may lead to achange in shape of the first and second electrode groups EG1 and EG2.The disposition and arrangement of the first signal line group SG1 andthe second signal line group SG2 may be substantially the same as thosein the input sensing layer ISL of FIG. 6B.

Since the notch region NTA is formed, the tenth electrode IE1-10 may bedivided into two portions, as shown in FIG. 13B. The two portions of thetenth electrode IE1-10 may be connected to each other through a dummyconnection line DSL. The fourth to sixth electrode IE2-4 to IE2-6 of thesecond electrode group EG2 may have a length shorter than that of otherelectrodes.

As shown in FIG. 14A, when viewed in a plan view, a signal transmissionregion HA may be defined in the display module DM. The signaltransmission region HA may be defined by partially or fully removing apartial region of each of the display panel DP and the input sensinglayer ISL. It is unnecessary for the signal transmission regions HA inthe display panel DP and the input sensing layer ISL to be the same. Thesignal transmission region HA may be a path, through which an opticalsignal passes. A plurality of the signal transmission regions HA may bedefined in the display module DM.

The signal transmission region HA of the display panel DP may be formedby removing at least a portion of the base layer BL and the circuitdevice layer DP-CL, the display element layer DP-OLED, and the upperinsulating layer TFL, which are disposed on the base layer BL. Thesignal transmission region HA of the input sensing layer ISL may be aregion, from which the sensor units SP1 and SP2 are removed.

As shown in FIG. 14B, the presence of the signal transmission region HAmay lead to a change in shape of the first and second electrode groupsEG1 and EG2. The disposition and arrangement of the first signal linegroup SG1 and the second signal line group SG2 may be substantially thesame as those in the input sensing layer ISL of FIG. 6B.

The signal transmission region HA of the input sensing layer ISL may bedisposed in a crossing region of the first and second electrode groupsEG1 and EG2. Here, a dummy connection line may be disposed near thesignal transmission region HA of the input sensing layer ISL. Forexample, the dummy connection line may form a detour near the signaltransmission region HA, thereby connecting the disconnected electrodesof the first and second electrode groups EG1 and EG2 to each other.

The unit region UA described with reference to FIGS. 7A, 7B, 7C, 8A, 8B,8C, 8D, 8E, 8F, 9A, 9B, 9C, 9D, 10A, and 10B may be applied to thesensing electrode of the first and second electrode groups EG1 and EG2shown in FIGS. 13A, 13B, 14A, and 14B.

According to an exemplary embodiment, a mesh line has cutting points,which are respectively disposed in a first direction and a seconddirection with respect to an emission region. Thus, it may be possibleto reduce a variation in visibility of the mesh line. The cutting pointsof the mesh line may have high reflectance to a source light, comparedwith other regions of the mesh line, and the brightness recognized by auser may increase in a direction or viewing angle, along which thecutting points are relatively more arranged. The cutting points may bedisposed such that they are not concentrated in a specific direction,and thus, it may be possible to reduce a dependence of visibility of themesh line on a viewing angle.

Border points may be formed on a border between electrodes, and suchpoints may result in a relatively high reflectance issue. Since thecutting points are disposed in the electrode, the border between theelectrodes may be hardly recognized. This is because an inner region ofthe electrode has reflectance similar to that of the border region.

Although certain exemplary embodiments and implementations have beendescribed herein, other embodiments and modifications will be apparentfrom this description. Accordingly, the inventive concepts are notlimited to such embodiments, but rather to the broader scope of theappended claims and various obvious modifications and equivalentarrangements as would be apparent to a person of ordinary skill in theart.
